Chem. Duine, unpublished results), the enzyme may indeed exist). Sie sind auf der linken Seite unten aufgeführt. ETF-QO is very highly conserved in evolution and the recombinant enzyme from the bacterium Rhodobacter sphaeroides has allowed the mutational analysis of a number of residues that the structure suggested are involved in modulating the reduction potential of the cofactors. Electron-transferring-flavoprotein dehydrogenase (ETF dehydrogenase or electron transfer flavoprotein-ubiquinone oxidoreductase, EC 1.5.5.1) is an enzyme that transfers electrons from electron-transferring flavoprotein in the mitochondrial matrix, to the ubiquinone pool in the inner mitochondrial membrane. electron transferring flavoprotein complex was observed, providing the first direct observation of these mammalian complexes. These experiments, together with the spectroscopic measurement of the distances between the cofactors in solution have confirmed the intramolecular pathway of electron transfer from ETF to ubiquinone. ►ETF:QO is an iron-sulfur flavoprotein linking central metabolism with the respiratory chain. https://doi.org/10.1021/bi800507p Robert J. Usselman,, Alistair J. Fielding,, Frank E. Frerman,, Nicholas … Cite this entry as: (2013) Electron Transferring Flavoprotein. Durch den oben genannten Mechanismus gelangen diese Elektronen zur Atmungskette. Synonyms. It is comparable in molecular weight and general properties to ETF-QO from beef heart [Ruzicka, F. J., & Beinert, H. (1977) J. Biol. Electron transfer flavoprotein dehydrogenase is involved in the process by which fats and proteins are broken down to produce energy. Heterodimeric electron transfer flavoprotein that accepts electrons from several mitochondrial dehydrogenases, including acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase (PubMed:27499296, PubMed:15159392, PubMed:15975918, PubMed:9334218, PubMed:10356313). Looking for abbreviations of ETF? (eds) Encyclopedia of Biophysics. Crystal … Energy Conservation via Electron-Transferring Flavoprotein in Anaerobic Bacteria Gloria Herrmann , Elamparithi Jayamani , Galina Mai , Wolfgang Buckel Journal of Bacteriology Jan 2008, 190 (3) 784-791; DOI: 10.1128/JB.01422-07 In humans, it is encoded by the ETFDH gene. Clinical mutations of ETF result in the … Das Heterodimer aus ETF-α und ETF-β ist dort für den Transport zweier Elektronen, welche durch FADH2 zur Verfügung gestellt werden, verantwortlich. Share this. Defects in electron-transfer-flavoprotein have been implicated in type II glutaricaciduria in which multiple acyl-CoA dehydrogenase deficiencies result in large excretion of glutaric, lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. Accepts electrons from ETF and reduces ubiquinone. The ETFDH gene provides instructions for making an enzyme called electron transfer flavoprotein dehydrogenase. It is Electron transferring flavoprotein. This is a preview … This process is experimental and the keywords may be updated as the learning algorithm improves. AU - Costas, Amaya M.Garcia. ETF fungiert hier als Elektronentransporter. ETF - Electron transferring flavoprotein. This gene encodes electron-transfer-flavoprotein, beta polypeptide, which shuttles electrons between primary flavoprotein dehydrogenases involved in mitochondrial fatty acid and amino acid catabolism and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists. This approach can be extended as the R. sphaeroides ETF-QO provides a template for investigating the mechanistic consequences of single amino acid substitutions of conserved residues that are associated with a mild and late onset variant of the metabolic disease multiple acyl-CoA dehydrogenase deficiency (MADD). Beim Menschen können Mutationen im ETFA- oder ETFB-Gen, die für die ETF-Untereinheiten kodieren, zur seltenen erblichen Glutarazidurie 2A (GA2A) führen.[1]. Biochemistry 38, 1977-89, (1999). Electron transfer flavoprotein-ubiquinone oxidoreductase (ETF-QO) is a 4Fe4S flavoprotein located in the inner mitochondrial membrane. Function i. Deficiencies in ETF or ETF-QO result in multiple acyl-CoA dehydrogenase deficiency, a human metabolic disease. ►Mutations in the UQ binding domain can cause a mild lipid storage myopathy that is riboflavin responsive. Electron bifurcation is the coupling of exergonic and endergonic redox reactions to simultaneously generate (or utilize) low- and high-potential electrons. Electron Transferring Flavoprotein, Beta Polypeptide listed as ETFB. Electron-transferring flavoprotein has been isolated from pig kidney by a simple procedure with a 7-fold higher yield over a previous method using pig liver. Dieses wird wieder zu FADH2 reduziert und gibt nun seinerseits die Elektronen an das in der mitochondrialen Innenmembran lokalisierte Ubichinon ab. Looking for abbreviations of ETFB?

Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. Heterodimeric electron transfer flavoprotein that accepts electrons from several mitochondrial dehydrogenases, including acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase (PubMed:25416781, PubMed:15159392, PubMed:15975918). This enzyme is normally active in the mitochondria, the energy-producing centers in cells. It catalyzes ubiquinone (UQ) reduction by ETF, linking oxidation of fatty acids and some amino acids to the mitochondrial respiratory chain.
